We issued our first set of Pipeline Rules in 1976. These Rules have been updated and revised a number of times, and the lates revision, DNV OS-F101 submarine Pipeline Systems (2000) is the most up-to-date pipeline standard worldwide. This Standard is supported by a number of Recommended Practices and Guidelines covering aspects such as strength of corroded pipelines, trawl board impact, freespan assessment and pipeline protection.

DNV offers a full range of verification and certification services based on the above standards, from verification of feasability and conceptual studies, to re-qualification and re-assessment of ageing pipelines.
